1. Those people or things (plural).
2. That person (singular). Usage as a singular pronoun is similar to the use of the word they as a singular pronoun; used as a reference to a person where sex (male or female) is unspecified or has not been determined. Used in this way because english doesn't have a singular form nonsexual pronoun.
